A recent playfield for quasi-crystals have bee realized by making 30 degree twisted bilayer graphene. This playfield has been extended as well using stackings of any 2 different moire systems into one, with a 30 degree misalignmnent between the respective moire angles.
- bedobi 5y agoAre you sure? My understanding was that perturbations resulting from subatomic crevasses in multi-dimensional lattices would render the impedance greater than the Yui-Schwarz limit.

Let me take some time to understand your comment. In the meanwhile, the whole field of superlaticces got a great boost with the first realization of moire systems using hBN, graphene and the like in 2013(?) by P. Kim and others. Before that, indeed, patterning superlattices from the bottom-up had been a laborious and mostly failing endeavor. If that's what you are referring too...
